patch 9.1.1297: Ctrl-D scrolling can get stuck
Problem: cursor_correct() calculates a valid cursor position which
is later changed by update_topline() and causes Ctrl-D
scrolling to be stuck (Daniel Steinberg, after v9.1.0258).
Solution: Update the valid cursor position before validating topline
(Luuk van Baal).
fixes: #17106
closes: #17110
